# class: RequestOptions
* since: v1.18
* langs: java

The [RequestOptions] allows to create form data to be sent via [APIRequestContext]. Playwright will automatically
determine content type of the request.

```java
context.request().post(
  "https://example.com/submit",
  RequestOptions.create()
    .setQueryParam("page", 1)
    .setData("My data"));
```

**Uploading html form data**

[FormData] class can be used to send a form to the server, by default the request will use `application/x-www-form-urlencoded` encoding:

```java
context.request().post("https://example.com/signup", RequestOptions.create().setForm(
  FormData.create()
    .set("firstName", "John")
    .set("lastName", "Doe")));
```

You can also send files as fields of an html form. The data will be encoded using [`multipart/form-data`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/POST):

```java
Path path = Paths.get("members.csv");
APIResponse response = context.request().post("https://example.com/upload_members",
  RequestOptions.create().setMultipart(FormData.create().set("membersList", path)));
```

Alternatively, you can build the file payload manually:

```java
FilePayload filePayload = new FilePayload("members.csv", "text/csv",
  "Alice, 33\nJohn, 35\n".getBytes(StandardCharsets.UTF_8));
APIResponse response = context.request().post("https://example.com/upload_members",
  RequestOptions.create().setMultipart(FormData.create().set("membersList", filePayload)));
```
